Great start of june - then 4th & 5th day downhill in clicks and CPC.
Adsense complexity has grown beyond control - would NOT be surprised at ALL if there's the same confusion in the Adsense control room.
The multi-dimensional tweaks of the past year has shaken the system into continuous instability & oscillations.
Of course not for premium publishers - they run good & ole pre-2011 adsense.
